In the field of intelligent security monitoring, network latency has always been a key issue affecting the monitoring effect. Whether it is the instant response of facial recognition access control, the real-time image transmission of drone inspection, or even the surgical guidance in telemedicine, delays may lead to information lag, affecting the accuracy and timeliness of decision-making.
As a provider of high-definition video secondary development solutions, Ruiloog Electronic’s independently developed VRS-UD350 network interface board (also known as: LVDS/MIPI to Network interface Board) effectively reduces network latency through a series of professional configuration strategies, providing strong technical support for intelligent security monitoring.
01 Delay challenge, the normal range of security monitoring
Network delay is composed of multiple factors, including propagation delay (the time required for a signal to travel through the transmission medium), processing delay (the time required for network devices to process data packets), queuing delay (the time a data packet waits to be processed), and transmission delay (the time required for a data packet to travel through the network).
However, in the intelligent security scenario, the delay of the VRS-UD350 network interface board is within the normal range.
02 Hardware Foundation: The inherent advantages of VRS-UD350
The VRS-UD350 network interface board is a high-definition video encoding and network transmission solution designed for SONY’s FCB series high-definition camera modules, such as the FCB-EV9520L and FCB-EV9500M. Its hardware design lays a solid foundation for low-latency transmission:
High-efficiency encoding capability: The VRS-UD350 network interface board supports dual-stream encoding of H.265/H.264. H.265 encoding saves bandwidth compared to H.264 under the same picture quality, indirectly reducing transmission delay and network pressure.
Multi-protocol support: The VRS-UD350 network interface board standardizes the SONY VISCA protocol to achieve unified control of the camera module (such as zoom, focus, and aperture adjustment), simplifying system integration and reducing the complexity of control command transmission.
Compact and compatible design: The VRS-UD350 network interface board is small in size and low in power consumption, making it easy to integrate into various security devices, including PTZ cameras, pan-tilt units and other devices that are sensitive to weight and space.
03 Core Strategy: Configuration Method for Reducing Latency in VRS-UD350
The following configuration can fully leverage the performance of the VRS-UD350 network interface board and significantly reduce network latency:
1. Optimization of encoding parameters
In the management interface of the VRS-UD350 network interface board, the encoding parameters can be adjusted according to the actual network conditions:
Bitrate and resolution adjustment: In an environment with limited bandwidth, appropriately reducing the bitrate or choosing a lower resolution can decrease the amount of data transmission, thereby reducing transmission latency. The VRS-UD350 network interface board supports flexible bitrate configuration strategies.
Frame rate adjustment: A higher frame rate (such as 60fps) can bring a smoother picture, but it will also increase the data volume. Adjust the frame rate based on the importance of the monitored content (such as whether it is moving at high speed) to strike a balance between smoothness and latency.
GOP length setting: Shortening the GOP (Group of Pictures) length can reduce the interval between keyframes (1 frame), lower decoding delay and video stuttering, and especially restore image quality more quickly when the network fluctuates.
2. Network transmission optimization
Protocol selection and optimization: The VRS-UD350 network interface board supports network transmission protocols such as RTSP, RTP/RTCP, and UDP. For scenarios with extremely high real-time requirements, the UDP protocol, due to its connectionless feature, usually has lower latency than the TCP protocol (avoiding the retransmission and confirmation mechanisms of TCP). However, UDP does not guarantee reliability and packet loss issues need to be handled at the application layer as required.
QoS (Quality of Service) configuration: Through the QoS function of network devices, higher transmission priorities can be assigned to the video stream data packets output by the VRS-UD350 network interface board. In this way, when the network is congested, video data can be processed and forwarded first, effectively reducing queuing delay and packet loss rate.
Bandwidth management: Ensuring sufficient network bandwidth is the foundation. Regularly conduct network bandwidth tests, reserve sufficient bandwidth based on the number of video channels and bitrate requirements, and avoid the network itself becoming a bottleneck.
3. Low latency mode is enabled
Some Sony FCB camera modules have a low-latency mode, such as the SONY FCB-EV9520L. In special circumstances, its low-latency mode can be enabled to achieve the purpose of low-latency video transmission.
04 Application Scenarios
Through reasonable configuration, the VRS-UD350 network interface board plays a significant role in various intelligent security scenarios:
Drone mobile security: The VRS-UD350 network interface board paired with SONY FCB-EV9520L is a cost-effective video solution for drone mobile security.
Remote monitoring: When paired with SONY FCB-EV9500M and VRS-UD350 network interface boards, a high-performance, long-distance transmission monitoring system solution can be built to meet the strict requirements of remote monitoring.
Smart Cities and Public Security: In large-scale public security monitoring networks, the VRS-UD350 network interface board facilitates long-distance data transmission, management, and line layout, ensuring the access and analysis of massive surveillance videos and enhancing the efficiency of the security system.
Summary
Through hardware optimization, software configuration and system collaboration, Ruiloog Electronic’s VRS-UD350 network interface board can also effectively reduce latency in intelligent security monitoring.
